Battle of Tri Phap

The Battle of Tri Phap was a battle of the Vietnam War which occurred from 12 February to 4 May 1974.

The NVA used the Cambodian border region between Kien Phong and Kien Tuong Provinces as one of its principal infiltration routes into South Vietnam, and activity in the swampy Tri Phap corridor of the region increased during the NVA offensives of late 1973 and early 1974. In February 1974, 3 South Vietnamese ARVN regiments launched a pre-emptive attack on the NVA forces at Tri Phap to forestall a massing of NVA troops for another offensive. The ARVN forces inflicted heavy losses on the NVA and overran their base area before more NVA reinforcements could arrive via the Ho Chi Minh Trail, protecting Saigon from assault and enabling them to focus on destroying the NVA presence in Svay Rieng as well.
